EMIL BOMMER, OF BROOKLYN, NEW YORK.

DOOR CLOSER.

Application filed July 1,

To all whom it may concern:

Be it known that I, EMIL BoMMEn, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Door Closers, of which the following is a specification.

This invention relates to door closers and has for its primary object to provide a simple and inexpensive device including a part adapted to be adjustably positioned with relation to the door whereby resistance may be offered to the swinging movement of the door from its closed towards an open position, or on the other hand, the door may be permitted to swing freely without such resistance.

With the and other objects in View, I have illustrated one practical embodiment of my invention in the accompanying drawing which will be hereinafter more fully described and subsequently incorporated in the subjoined claims.

In the drawing wherein similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a fragmentary elevation of a door and part of the door jamb with my device applied thereto;

Figure 2 is a bottom broken away;

Figure 3 is a fragmentary perspective View of the essential portion of the device;

Figure 4 is an enlarged detail perspective view of one of the parts;

Figure 5 is a transverse section taken on the line 55 of Figure 4; and

Figure 6 is a sectional view taken on the line 66 of Figure 5.

Referring in detail to the drawing, 5

plan view partly 'designates a part of the door which is hingedly mounted at one of its edges for swinging movement relative to the door jamb 6.

Upon the j amp o the bracket plate 7 is secured by screws 8, said bracket plate having horizontal outwardly projecting ears 9 and 10 respectively at its upper and lower ends. Between these ears the cylindrical barrel or housing 11 for a coil spring is arranged. Between the opposite ends of the cylindrical barrel 11 and the ears 9 and 10 respectively, the collars 12 and 13 are arranged, one end of the spring within the barrel being connected to the collar 12. The construction, mounting and arrangement of the parts 11,

12 and 13 with the spring contained in said barrel is well known in the art of spring hinges, and therefore, need not befurther described. For the present explanation, it will suffice to state that the collar 12 has a laterally projecting arm 14 thereon, the lower side of which has a groove or channel 15 therein, the side walls of said channel being connected at their upper edges at the end of the arm as at 16. At the inner end of the channel the lower wall thereof provides a seat 17, the surface of said seat having a transverse groove or channel 18 out therein.

A rod 19 has each of its ends upset or enlarged as indicated at 20 and 20 respectively. When the rod is disposed in a horizontal position, one of its ends is seatedupon the seat 17 of the'arm 14 and the enlarge-- ment on the ends of the rod is engaged'in the groove 18 of said seat. As illustrated, I have shown the device mounted upon the left hand jamb of the door and therefore, the enlarged end 20 of the rod is engaged in said groove. When the rod is in its horizontal position, such enlargement prevents longitudinal movement ofthe rod upon its seat'and when the rod is disengaged from said seat, it is slidably moved with respect to the arm 14, the enlargement 20 engaging the one side of the arm to limit such sliding movement of the rod and sustain said rod in a pendant vertical position. When the bracket and collar 12 are arranged upon the right hand 'door jamb, they are inverted from the position shown in the drawing and in such case the other enlarged end 20 of the rod 19 serves to limit sliding movement of the rod to its vertical position and prevent disconnection of said rod from the arm.

Upon the face of the door 5, a roller 21 is mounted in a suitable bracket 22, said roller being peripherally grooved and the rod 19 when in a horizontal position, being held in this groove of the roller by the spring contained in the barrel 11, which spring is connected to the collar 12.

From the above description, it will be readily seen that when the rod 19 is disposed asshown in Figure 1 of thedrawings so that it bears against the grooved roller 21 and the end thereof is lockedin connection with the arm 14 on the collar 12, when the door 5 is swung towards an open position, the roller 21 will ride along the rod as said rod is swung laterally with the door. In

such swingingmovernent of the door and the rod the collar 12 is rotated so that the spring in the barrel 11 is placed under a gradually increasing tension. Therefore, a

gradually increasing resistance is applied as the door is moved towards its extreme. openposition.

When it is desiredto permit of the'fr'ee-- swinging movement of the door without such resistance, it is only necessary to disengage arm 14 so thatisaid rod will hang loosely in perpendicular position, asshown indott'edlines in Figural of thedrawings with the flange- 20 engaged upon theside oftlie'a rni 14. Thusthe rod is supported closely adja-- a cent to the face of the door'jamb and out of" the path of movement-of the doorso that the latter may be freely swung to any'desired degree" towards its'operr position and remain in such position;

V The device-as above left side ofthe door, itbeing-only necessary jambi" to invert= the-'position= of the device so that;

the armfil l will beat the lower end thereof wheirthe As, above explained the rod '19 cannot-becomedisconnected from the arm 14; in either position ofsaid' arm upon theriglit orrleft hand door jainb by reason" of the enlarged ends 20 'and 20* of said rod, and it isunderstoodof course thattheroller 21 is properly positioned on thedoor' face so' that the-rod will engage therewith when disposed in its horizontal position;

From the fore oing description I considered' in'conn'ection with the accoinpanyingf drawings, thefseveral essential features of the device will be clearly understood to-' gether with the-advantages thereof; Owing to thesimple form and construction of" the several co-operating'elements itwili be seen that'sucha device" is exceedingly durable,- not likely to get" out of order and positive and reliable i-n the performance of its functions."

Vvlii le l'have herein shown and described a preferred embodiment of myinvention, it will neverthelessbe understood that the same is susceptible of" embodiment'in other alternative constructions, and I thereforereservethe privilege of resorting to all such legitimate changes as may be fai-rly embodied within the spirit and scope of the iiivention' as claimeds I claim:

L'In combination, a spring heldmem ber mounted uponadoor jamb for movement inahorizOntaP-plane and having a laterdescribed can be fl V plied to the jams ateither the right or the device is applied to a right hand under tension whereby. in the swinging movement ofthe door, saidspring held member lSl'OtlLtGCl and resists-said swinging move' ment ofthe door, said rod 'adapted to be moved from said horizontal position to a vertical position and the enlarged-head on the end of the rod engagingxt'he upper side of said channel'ar'm to sustain the rod 'in such vertical position. i f i 2.;ln combination, a spring held inen'k ber'mounted upon a door jamb foi rotarymovement in a horizontal plane-and having a-laterally projecting arm provided'with 'alongitudinal channel open on one side andliaving a seatatih'e' inner cnd thereof,

3. In combination. a bracket and a spring held collar rotatably mounted in one end ofsa-id bracket, said bracket and collar being invertible for arrangement upon either a right or left hand door jamb, said collar having a laterally projecting arm thereon, a rod slidably and permanently connected with said arm and having: an enlargement formed on each of its ends, said arm having a seat upon which one endof said rod is adapted to be engaged and a groove formed in said seat to receive the enlargementon one end of the rod :when saidjrod is disposed in a horizontal position, said rod when disengaged from said seat being: slidable with respect to said arm and the enlarge ment on one end of said rod coacting with the arm to prevent disconnection of the rod therefrom and sustain said rod in a pendent vertical position, and a roller adapted to be mounted on the face of a door to engage said rod when the rod is horizontally positioned with respect to said arm.

I. In combination, a spring, a member held thereby and adapted for movement in a horizontal plane against the resilient action of the spring, a lateral projection extending from said member, an arm carried by said projection with one or the first end engaging the projection and its other or second end hanging downwardly therefrom, and means for holding said arm in said pr0 jection so as to project laterally thereof by positioning the arm therein with the said second end thereof engaging said projection and its first end extending laterally outward therefrom.

5. In combination, a spring, a member held thereby and adapted for movement in a horizontal plane against the action of the 1 spring, a laterally projecting arm formed with a longitudinal channel having a recess providing a socket in the inner end thereof, a rod provided with an enlarged head on one end and adapted for engagement upon said socket when said rod is disposed in a horizontal position and adapted to be moved from said horizontal position to a vertical position and the enlarged head on the end of the rod engaging the upper side of said channel arm to sustain the rod in such vertioal position.

6. In combination, a spring, a member -held thereby and adapted for movement in a horizontal plane against the resilient action of the spring, a lateral projection extending from said member, an arm slidingly carried in said extension adapted to extend horizontally therefrom and to slide therein so that either of its ends will engage said extension and means on the ends of the arm to prevent its removal from said extension.
